METALLIC COUPLING F03 'rHn CONVEYANCE on FLUIDS nn'rwnnnvnnr'cnns 'To ulllvh'mnt't may concern:

Be it known that I, HENRY hams STUART Msn'rrx, a subject of the King of Great Britain,'residing at- 271 Dclormier avenue, in the city of Montreal, in the District of lvlontreal, in the Province of Quebec, in the Dominion of (an-aria, have invented certainnew and useful Improvements in Metallic Couplings for the Conveya'nce of Fluids Between Vehicles, of which the following is a specification. I

' This invention relates to improvements in metallic couplings for the conveyance of fluids between vehicles.

The invention consists essentially of a plurality of ring and socket joints interposed in a iiniversal arrangement of pipes between two vehicles.

The objects of the invention are to devise a coupling inwhich thcinaintenance charges will be reduced to the minimum and to provide flexibility without enrlangering thefluid tight connections.

In the drawings, Figure 'l. is a perspective view of the coupling showing the connections to the vehicles. Fig.

- is a longitudinal sectional view of the middle and tele- Iscopically'arranged pipes. Fig. 3 is a vertical sectional view of the joint at the point of connection with the pipe attached to the vehicles. Fig. 4 is a longitudinal soction of an intermediate joint.

. Like letters of reference indicate corresppnding parts in each figure. v Referring to the drawings, a is 1...; locomotive and!) the tender and c and d bracketsdepending from said locomotive, and said tender respectively and supporting the pipes e and f, the pipe 0 leads to the injector of the locomotive and the pipe leads from the water supply in the tender. I V

g and h are lazy-cocks at the ends of the pipes e and f.

t are joint members having extending from one side thereof the sleeveportions j internally threaded and screwing on to the coirespondingly threaded ends of the pipes e and f. k are screw plugs closing orifices correspondingly threaded at the bottom of the basin portion 1 of the chambers containedwithin the joint mem bers m are annular recesses encircled by the flanges n. at the top and open end of the joint members i.

a are pipes or tubes having at their-inner ends the ringsp preferably brazed thereon and fitting snugly into 'theatnnular recesses m and forming journal hearings on which said flanges nturn. v

q are sleeves encircling the pipes 0 and having at their lower ends the lateral flanges r and bolt holes through said lateral flanges r registering with corresponding bolt holes through the annular flanges 1L and firmly secured to said flanges n by the bolts s thus inclosing the rings p securely in their journals. Th e sleeves q flaring outwardly at thave the upwardly extending enlarged por- Specifioation of Letters Patent.

pipes and said upward extensions the annularfi jrd boxes 1). j i

ware packing rings of any suitable, material and circling the pipes-o at the lower boxes 1). i

a; are gland members encircling the pipes 0 and extending downwardly into the gland boxes na'butting said packing ring and completing the gland and having end of the said I the lateral flanges y and suitable bolt holes through said flanges y registering with bolt holes through the lateral flanges 2 at the top of the upward extensions u and secured to said flanges z by the bolts 2 extending through the aforesaid bolt holes.

It 'will be thus seen that the joints formed with the pipes e and f and the pipes o are 4 complete. One member of said joints, viz'1the rings p being on the end. of the said pipes, the other members i being firmly secured to the said pipes e and f, and

as all movements will beconfined to the vehicles caused by their varying positions in relation one to the other I and the vibratory motions thereof, the joint members i will in their re'cc-sserLportions form the journal bearsocket portion. 1

The Pipes 0 at the upper bows 3 secured thereto and secured to the outer end,

7'5 ing'on the rings p. The glands in the sleeves q will effectually pievent any leakage through the ring and ends thereof have theelof the elbows 3 are the pipes 4 arranged at right angles tothe pipes o. The pipes 4 have the lateral flanges5 and annular recesses 6 in said flanges corresponding to the recesses m aforesaid.

7 are pipes having the rings 8 brazed thereon at the end thereof and fitting turning therein. 4

9 are sleeves having the fianges 10 secured to the flanges 5 and the enlarged extensions 11 forming the glands 12 of precisely similar formation to the aforesaid glands in the sleeves q.

The pipes 7 extend along to the elblowsjli, which have the pipes 14 extending therefrom to the elbows 15, which in turn have the .pipes T6 extending therealong parallel to thepipes 7, to the elbows 17 and from the elbows 17 extend the telescopic pipes 18 and 19 having the gland 20 formed at the enlarged end .21of'the snugly into the recesses' 6 and pipe 18. In this arrangement of pipes and joints a universal coupling for the passage of water or'other fluids iseffected, as no matter what position the tender may assume in relation to the locomotive, the combi- Y nation of the turning of the joint members i on therings p and the rings 8 in the recesses 6 rind the drawing inwardly and outwardly of the pipes 18 and will accommodate any'such position. i

The difficulty in metallic couplings in thepast been chiefly in the arrangements of joints, thatis to ob-" tain some form of flexible connection wherebythe jolting' and jarring of the vehicles will not cause a leakinithat connection and besides will not be a constant trouble and expense as regards maintenance; In the present invention these troubles are all obviated, as the simplicity of the flexible connection, and the arrangement of the pipes provide a permanent coupling,

- which will not shake to pieces or become d'isarranged thereof containing the essential features of the invention could be equally as well applied for the conveyance of compressed air or steam or other fluid between vehicles, and without departing from the spirit of 'my invention the arrangement of the pipes or the placing of the joints may be materially altered. I 'jAn'other advantage may be mentioned in connection with this invention, and that is in the event of the part,-

ing of the tender from the locomotive through accident for in case of such an event, all that happens to the coupling is that the pipe 19 draws out from the pipe 18,

I i and through the intermediate joints, the ends drop to-an angle of about forty-five degrees, thus eliminating any-chance of breakage to the coupling on the sudden bringing together again of the locomotive and tender. What claim as my invention is: ,1. in a device of the'class described, in combination, a fluid pipe supported by a vehicle, a fluid pipe supported by a vehicle following theaiorcsaid vehicle, a pair of joint. members secured to the open ends of each of the aforesaid pipes respectively, a pair ofpipes having joint members inserted ill the aforesaid joint members respectively and suitably secured therein, said pipes extendlngffrom the vehicle pipes and at right angles thereto and extending in a further length at right angles to the length directly con-v nected to the vehicle pipes and forming U-shnped bends and terminating in pipes telescopically arranged, and at right angles to said U-shuped bend and a pair o joints interposed in each of the second lengths of pipe, said joints having a rotary motio 'n, as-and for the purpose specified.
